| 摘 要： | 采用光学被动式无热化设计方法,给出了针对长波红外制冷型光学系统的一个设计实例.该系统采用了576元线列探测器,相比于以往288元线列探测器而言,在相对孔径、焦距等参数不变的条件下,视场扩大了一倍.该系统F数为1.6,焦距100 mm,视场9.2°,实现了100%的冷光阑匹配.设计结果表明,该系统在-50℃～+90℃的宽温度范围内,像质接近衍射限,无须任何调焦,无热化性能良好.

| Abstract: | Based on athermal design technologies of optical passive mode,this paper describes an example of a cooled long wave infrared optical system.This system adopts a linear IRFPA with 576 pixels.Compared with old linear IRFPA with 288 pixels,the larger pixel number results in a larger field of view with same parameters such as numerical aperture,focal length,etc.The F number is 1.6,the focal length is 100mm,and the FOV is 9.2?.This system has a 100% cold-shield-match.The result shows that the image quality of th... |
